| 摘要 | PURPOSE:To prevent a sealing material from being peeled off by forming fine grooves communicating between opening sections and the outside on the sealing material sticking face of a case and covering and sticking the sealing material on the opening sections and the fine grooves. CONSTITUTION:Fine grooves 9 communicating between opening sections 7 and the outside are formed on the sealing material sticking face 1c of a case so that the case interior and the outside air are communicated through the fine grooves 9 when the sealing material 8 is stuck. Even if the air in the case 1 is expanded when processings such as preliminary heating, flux coating, dip soldering are performed, the inside air is released to the outside through the fine grooves. The sealing material 8 is thereby prevented from being peeled off due to the abnormal rise of the air pressure in the case 1. Air vent holes are formed with the fine grooves 9, thus the infiltration of dust or a cleaning liquid can be surely prevented. | ||||||
